21700x4 Battery Pack

Description

Big Blue's higher-output video lights moved to the 21700 cell because a four-cell 18650 pack could not hold enough energy to run them for a useful dive. This is the lithium-ion rechargeable four-cell 21700 pack for that group: the CB7200P, CB11000P, CB7200PB, CB11000PBRC, VTL13500P Max, TL8000P Mini and VL15000PBRC. It is supplied as a sealed assembly rather than loose cells, which keeps them balanced and the light's regulation predictable. A spare pack is the only realistic way to run a second dive on the same day, because charging is measured in hours and a swap in seconds, and a video light drains far faster than a torch. Note it is not interchangeable with either of the four-cell 18650 packs despite the similar description. A matching charger is sold separately. It suits an owner of any of those seven lights.
